In the current model, each cached Gradle User Home could contain
a copy of one or more downloaded wrapper distributions. This results
in large cache entries which could easily lead to premature eviction.
With this change, wrapper dists are cached separately from the rest
of the Gradle User Home directory. The artifact file is replaced by
a marker file which allows the action to restore the artifact from
cache when the Gradle user Home cache is restored.
Attempt to capture as much context as possible about the job run
to generate a unique cache key. Unfortunately much of the matrix context
is not available to the action implementation.
This will eliminate cache entries from previous workflow runs, allowing
us to test cache functionality in isolation. If the `CACHE_KEY_SEED` environment
variable is not set, this will have no impact.
The Gradle daemon is not useful for ephemeral builds, and the process
can hold file locks which interfere with cache entry generation.
In the case where multiple Gradle invocations occur in the same job,
we could provide a way for users to override this behaviour, taking care
of stopping any daemon process at the end of the job.
- Do not restore cache when GUH exists
- Include RUNNER_OS in the cache key
- Do not save cache on exact hit
- Only save cache in the final post action
- Log before saving cache
Cache keys have a hard limit of 512 characters, so we need to ensure that we don't generate a key longer than this.
- Remove excess whitespace
- Truncate to 400 characters
Fixes#70
This makes the version alias match other places where we reference a release candidate version.
The 'rc' alias is still supported, but emits a deprecation warning.
- Cache is separate from (but similar to) the wrapper distribution cache
- New 'distributions-cache-enabled' flag controls caching of all downloaded distributions
(including wrapper distributions)
- Deprecated the 'wrapper-cache-enabled' flag for removal in v2
Prior to this change, the wrapper cache contained both the downloaded zip
file as well as the exploded wrapper dir. Only the zip file is required,
as Gradle will automatically detect and unpack.
- Provide a more useful error message when no Gradle wrapper can be located,
and 'gradle-version' or 'gradle-executable' is not used.
- Add test for case where wrapper is missing.
This isn't really a "test" per-se, but this failing build invocation makes it
easy to verify the GitHub action behaviour when the build is misconfigured.
